Four weeks ago I mentioned a dog crashed me out of the evening commute. I ended up with a separated left collarbone and fractured right wrist.
3 weeks out I was able to get back on the bike for short rides and commuted with my MTB and panniers (I usually use a backpack). Four weeks out and I can use the backpack and have been able to handle 50+ mile rides.
The doc says he is amazed at my recovery and range of motion (nearly normal) because they said it was nearly a level-five separation - all ligaments torn and 100% displacement of the end of the collarbone upwards.
It is still like that - I have a permanent golf-ball sized lump on my left shoulder where the end of the collarbone is sticking up. It is still sore locally, and the muscles are weak in that shoulder - can't lift anything over about 10 pounds without pain. Even opening a door is a bit painful, so I use the right hand for all that.
But at least I can ride. The summer is shot as far as the events I wanted to do - mainly double centuries - because I lost a lot in the four weeks It sucks to be older and have slow recovery time.
Anyway, it was not as bad as it could have been, I guess.

Yah - at least you are out. I lost the end of last year myself - From the start of August til January. It takes a while to come back, and sucks to miss good time out. But you can ride now, so that is good. I had to find something else to do, which was a little tricky.
